The English band will preview the tour and album with a March 11 (that is, tonight) performance on TV's "The Late Show with David Letterman." The trio's "Letterman Show" appearance will be preceded at 5 p.m. today by a "Live On Letterman" multi-song set webcast on CBS.com and VEVO. Not conicidentally, VEVO is an official media sponsor of the North American leg of Depeche Mode's "Delta Machine World Tour."

That leg of the tour opens Aug. 22 in Detroit and concludes Oct. 8 in Phoenix. Tickets for all concert dates, including the San Diego show, go on sale April 6 to the general public at livenation.com. There will also be a number of pre-sales.

Fans who purchase or pre-order Depeche Mode's "Delta Machine" album on or before April 1, from amazon.com, will receive a special pr-sale code to buy two tickets, between April 3 and April 5, for any show on the tour.

In addition, Live Nation mobile app users will have access to pre-sale tickets on Friday, April 5th at 10 AM. Mobile users can text “LNAPP” to 404040 to download the Live Nation mobile app. (Available for iOS and Android.)

This will be Depeche Mode's first concert trek since its 2009/2010 "Tour of the Universe." In a release issued Monday morning, band members Martin Gore and Dave Gahan expressed excitement about hitting the road again.

"I enjoy being in front of an audience because our songs really take on a life of their own when performed live," Gore said. "When we’re performing, the stage almost becomes a mirror for the people who have been there since the beginning, and we become a reflection of our audience. I’m looking forward to this tour for that very reason.”

Added Gahan: “I’m really looking forward to getting out there and performing. There are so many die hard Depeche Mode fans who have been with us every step of this journey that I can’t wait to see. I also hope that we gain some new fans with the release of Delta Machine, and I look forward to exposing them to a great Depeche Mode live performance."
